Some of the UK's top sports pundits can't stop ripping off their shirts after whipping their abs into shape.Sky Sports’ Alex Payne was one of six broadcasters to compete in Men’s Health magazine's annual Celebrity Six-Pack Challenge.The most unlikely of men have been transformed into cover model stars thanks to the fitness initiative and the 31-year-old is no exception.He admitted that at first it was a struggle bulking up his 'lean frame' but he soon managed to schedule in daily workout sessions.'I wouldn’t have done this if it weren’t for the element of competition. I genuinely thought I was going to die after the first gym session but I don’t think I really hated any of it.'I got some very strange looks from the boys in the commentary teams when I started tucking into a protein shake at half time,' he told Men's Health.

'My wife went away for a few days and was shocked when she got back.'Meanwhile the oldest contestant, former pro-footballer and exuberant Sky pundit Chris Kamara, 54, added: 'The last time I had a six-pack was 30 years ago and it’s been 20 since I lifted a weight.
